I'm 99% sure on this, but if you divide the combustion chamber volume when the piston is at bottom dead center and divide it by the volume at top dead center that should get you your compression ratio.
Another interesting fact you may ask about is long stroke vs. short stroke. A square is when the bore equals the stroke, longer stroke is as it sounds. A longer stroke has better low end torque, but lower reving while a short stroke has lower torque but can rev higher. In most engines toyota is a long stroke while most civice are short or square (I think). Hope this helps. |
